Answer:

(-2, -2)

Step-by-step explanation:

The midpoint M is calculated from end points A and B as ...

M = (A +B)/2

Solving for end point B, we get ...

2M = A +B . . . . . . multiply by 2

B = 2M -A . . . . . . subtract A

Then the other end point is ...

B = 2(4, 3) -(10, 8) = (2·4 -10, 2·3 -8) = (8-10, 6-8)

B = (-2, -2)

The other end point has coordinates (-2, -2).

Answer:

Step-by-step explanation:

$\frac{1}{1-x^{a-b}}+\frac{1}{1-x^{b-a}}\\\\\frac{1}{1-x^{b-a}}=\frac{1}{1-x^{-(a-b)}}=\frac{1}{1-\frac{1}{x^{a-b}}}\\=\frac{1}{\frac{x^(a-b)-1}{x^(a-b)}}=\frac{x^{a-b}}{x^{a-b}-1}\\\\=\frac{x^{a-b}}{-(1-x^{a-b})}=-\frac{x^{a-b}}{1-x^{a-b}}\\\\\frac{1}{1-x^{a-b}}+\frac{1}{1-x^{b-a}}=\frac{1}{1-x^{a-b}}-\frac{x^{a-b}}{1-x^{a-b}}\\\\=\frac{1-x^{a-b}}{1-x^{a-b}}=1$

two men start from 2 places 600km apart and travel towards each other, the first travelling 5km/h faster than the other. they me

Gekata [30.6K]

If they meet after 8 hours, then the sum of their average speeds is 600/8=75 km per hour. If one is 5 km per hour faster than the other, then if we set the speed of the slower man to x, we have:

2x+5=75

So:

2x=70

x=30

The fastest man is 5 km per hour faster than the slower, so he travels 35 km per hour.
